This book has been written especially for these newcomers to CP/M. CP/M software never exactly fits your precise needs so some 'patching' is always desirable. You need, however, to have some knowledge of CP/M assembly language in order to adapt CP/M programs (including the large amount of free 'public domain' software available) to your needs. This book, therefore, deals with the CP/M structure and how simple CP/M machine code programs can be written with the assembler editor package supplied with the machine. Numeroous useful routines and listings are provided, and the book is written in a straightforward style which you should find easy to follow.
